A de Dion axle is a form of non- independent automobile suspension . It is a considerable improvement over the swing axle , Hotchkiss drive , or live axle . Because it plays no part in transmitting power to the drive wheels, it is sometimes called a "dead axle".
67-474: The Pegaso Z-102 is a Spanish sports car produced by Pegaso in Spain in both coupé and cabriolet form from 1951 until 1958. The Z-102 was the fastest car in the world at the time of production, having reached a top speed of 151 mph (243 km/h). Pegaso was an established company noted for its trucks and motor coaches, but also produced sports cars for seven years. Pegaso's chief technical manager
134-412: A 5-speed non-synchromesh transaxle. The Z102 entered production with a 2.5 (2,472 cc) litre engine, as was used in the prototypes, though later variants used a 2.8 L (2,816 cc), and 3.2 L (3,178 cc) litre DOHC desmodromic 32- valve V8 360 hp (268 kW) engines with multiple carburetors or an optional supercharger. Power ranged from 175 hp (130 kW) to 360 hp (268 kW) and
201-487: A De Dion rear axle with leaf springs. The 2024 Mercedes-Benz EQG (G580 EQ) also uses a De Dion type rear axle, with double universal joint driveshafts transferring drive propulsion from the electric motors and incorporating slip joints to equalize the length. Most models of the Kawasaki MULE line of utility vehicles feature a leaf-sprung de Dion rear suspension with a distinctively curved tube axle that clears

335-399: A controversial choice for a "purist" sports car. The Elan sold poorly and was discontinued after three years. The 1996 Lotus Elise , a mid-engined, rear-wheel drive roadster, was much more successful and remained in production until 2021. Roadsters enjoyed a resurgence in the mid-1990s, including the 1989-present Mazda MX-5 , the 1995-2002 BMW Z3 (succeeded by the 2002-2016 BMW Z4 ),
402-409: A definition. Insurance companies have also attempted to use mathematical formulae to categorise sports cars, often charging more for insurance due to the inherent risk of performance driving. There is no fixed distinction between sports cars and other categories of performance cars, such as muscle cars and grand tourers , with some cars being members of several categories. Traditionally,
469-496: A handful of cars had bodies by other coachbuilders. Carrozzeria Touring's design built on Ricart's original design, with changes including redesigning the grille, lowering the car, re-positioning the fog lights and simplifying various details to give it a cleaner profile. This body style is the most well known and numerous of the Z-102 bodies. French coachbuilder Saoutchik bodied 18 cars, 3 of which were convertibles, as well as one of

Three Z-102s were entered by Pegaso in the 1953 24 Hours of Le Mans (some sources claim the number was 4, and others claim only 2 entered), but during the race driver Juan Jover misjudged the speed of his approach to the corner after the Dunlop bridge, causing him to crash his Z-102 Spyder into the barriers at more than 200 km/h (120 mph). He sustained serious injuries to his left leg from
737-491: A total of 84 cars (some sources say only 71). Out of those 84, 28 were cabriolets while the rest were fixed-roof coupés. The original design for the Z-102 was penned by Pegaso chief technical manager and automotive engineer Wifredo Ricart , formerly chief engineer for Alfa Romeo . 19 cars were bodied by Pegaso's parent company Enasa, 11 of which were Berlinettas. The majority of Z-102s had bodies by Carrozzeria Touring (although early Z-102 units carry Pegaso-made bodies), but

#1732793316881804-452: Is an iconic sports car of the early 1960s, due to its attractive styling and claimed top speed of 241 km/h (150 mph). The E-type was produced for 14 years and was initially powered by a six-cylinder engine, followed by a V12 engine for the final generation. In 1962, the MG B introduced a new era of affordable lightweight four-cylinder roadsters. The MG B used a unibody construction and
871-413: Is not intended to flex. In suspension geometry it is a beam axle suspension . The de Dion axle was named after Comte Jules-Albert de Dion , founder of French automobile manufacturer De Dion-Bouton . The axle, however, was invented around 1894 by co-founder Charles Trépardoux , Georges Bouton 's brother-in-law, for use on the company's steam tricycles. Advantages: Disadvantages: Alfa Romeo

Other production vehicles using this suspension include the Lancia Aurelia (fourth series onwards) and Flaminia , first and second generation Prince Gloria , the original Mazda Cosmo , Volvo 300-series , Rover P6 , Chrysler minivans (all wheel drive versions from 1991 to 2004), DAF 46 , DAF 66 , all Iso cars ( Iso Rivolta IR 300 , Iso Grifo , Iso Fidia , Iso Lele ) and early Bizzarrini 5300 GT Stradas , some of
1072-520: The Audi RS 2 Avant . Ford Europe withdrew from the sports car market at the end of 1986 when the Capri was discontinued after a production run of nearly two decades. There was no direct successor, as Ford was concentrating on higher-performance versions of its hatchback and saloon models at the time. In 1989, a new generation of Lotus Elan roadster was released which used a front-wheel drive layout,
1139-541: The BMW 303 , Citroën Traction Avant and Fiat 508 — offered similar handling and comfort to the more expensive sports cars. Powerful, reliable, and economical (although softly suspended) American saloons began to be imported to Europe in significant numbers. Sports car ownership was increased through models such as the Austin 7 and Wolseley Hornet six , however many of these sports cars did not offer any performance upgrades over
1206-623: The Bentley Speed Six (1928-1930), with the former famously described by Bugatti's founder as "the fastest lorry in the world". Between the Great Depression and the World War II the pre-war era was a period of decline in importance for sports car manufacturers, although the period was not devoid of advances, for example streamlining . Cheap, light-weight family sedans with independent front suspension— such as
1273-593: The Caterham 7 (a development of the Lotus Seven after Lotus sold the design rights to Caterham Cars ), are the only cars recently in production that use this arrangement, as well as the products of some kit car companies. A recent vehicle to use this suspension coupled with leaf springs was the Ford Ranger EV . The American-built MV-1 van by VPG, produced from 2010 to 2016, also used this suspension in
1340-520: The Jensen FF became the first sports car to use all-wheel drive . The Ford Capri is a 2+2 coupe that was produced from 1968 to 1986 and intended to be a smaller European equivalent of the Ford Mustang. A main rival to the Capri was Opel Manta , which was produced from 1970 to 1988. The 1973-1978 Lancia Stratos was a mid-engined two-seat coupe that was powered by a Ferrari V6 engine. This

Early motor racing events included the 1903 Paris–Madrid race , the 1905-1907 Herkomer Trophy, the 1908-1911 Prince Henry Tour and the 1911–present Monte Carlo Rally . The Prince Henry Tours (which were similar to modern car rallies) were among
1541-495: The 1921 Coppa Florio . Another approach— such as that used by Morris Garages— was to convert touring cars into sports cars. The first 24 Hours of Le Mans race for sports cars was held in 1923, although the two-seat sports cars only competed in the smallest class, with the majority of cars entered being four-seat fast touring cars. "This race, together with the Tourist Trophy Series of Races , organised after

In the 1970s, turbocharging began to be adopted by sports cars, such as the BMW 2002 Turbo in 1973, the first Porsche 911 Turbo in 1975, and the Saab 99 Turbo in 1978. Turbocharging became increasingly popular in the 1980s, from relatively affordable coupes such as
1742-452: The 1980–1986 Renault Fuego and 1992–1996 Rover 220 Coupé Turbo , to expensive supercars such as the 1984-1987 Ferrari 288 GTO and 1987-1992 Ferrari F40 . In the late 1980s and early 1990s, several manufacturers developed supercars that competed for production car top speed records . These cars included the 1986–1993 Porsche 959 , 1991–1995 Bugatti EB 110 , 1992–1994 Jaguar XJ220 and 1993–998 McLaren F1 . The 1980-1995 Audi Quattro
1809-506: The 1990s, all-wheel drive has become more common in sports cars. All-wheel drive offers better acceleration and favorable handling characteristics (especially in slippery conditions), but is often heavier and more mechanically complex than traditional layouts. Examples of all-wheel drive sports cars are the Lamborghini Huracan , Bugatti Veyron , and Nissan GT-R . Rear engine layouts are not typical for sports cars, with

Following the halt in sports car production caused by World War I , Europe returned to manufacturing automobiles from around 1920. It was around this time that the term 'Sports Car' began to appear in the motor catalogues, although
2345-400: The early 1920s, the cost to produce a racing car was not significantly higher than a road car, therefore several manufacturers used the design from the current year's racing car for the next year's sports car. For example, the 1921 Ballot 2LS based on the racing car that finished third at the 1921 French Grand Prix. The Benz 28/95PS was also a successful racing car, with victories including
2412-463: The exact origin of the name is not known. The decade that followed became known as the vintage era and featured rapid technical advances over the preceding Brass Era cars . Engine performance benefited from the abandonment of " tax horsepower " (where vehicles were taxed based on bore and number of cylinders, rather than actual power output) and the introduction of leaded fuel , which increased power by allowing for higher compression ratios . In

Examples of MR layout sports cars are the Ferrari 488 , Ford GT , and Toyota MR2 . To avoid a front-heavy weight distribution , many FR layout sports cars are designed so that the engine is located further back in the engine bay, as close to the firewall as possible. Since
2881-544: The most common layout for sports cars was a roadster (a two-seat car without a fixed roof). However, there are also several examples of early sports cars with four seats. Sports cars are not usually intended to transport more than two adult occupants regularly, so most modern sports cars are generally two-seat or 2+2 layout (two smaller rear seats for children or occasional adult use). Larger cars with more spacious rear-seat accommodation are usually considered sports sedans rather than sports cars. The 1993-1998 McLaren F1

The front-wheel drive layout with the engine at the front ( FF layout ) is generally the most common for cars, but it is not as common among traditional sports cars. Nonetheless, the FF layout is used by sport compacts and hot hatches such as the Mazdaspeed3 . Sports cars with an FF layout include the Fiat Barchetta , Saab Sonett , or Opel Tigra . The ancestor of all high-performance cars had its origin in Germany. The 28-h.p. Cannstatt-Daimler racing car of 1899

Enasa also built a version of the Z-102 called the "Cupola" which was designed based on sketches from Spanish students. The students were given the challenge of sketching what they thought cars of the future would look like. Prominent design cues from those drawings were then taken, and Enasa brought the car to life. Only two "Cupola" models were known to have been built. One of

Then by the late 1920s, the cost of producing racing cars (especially Grand Prix cars) escalated, causing more manufacturers to produce cars for the growing sports car market instead. Significant manufacturers of sports cars in

The Mitsubishi Fuso eCanter uses
3417-558: The sporting events of the period, bringing renown to successful entrants. The Prince Henry Tours started the evolution of reasonably large and technically advanced production sports cars. In England, the development of sporting cars was inhibited by the Motor Car Act 1903 , which imposed a speed limit of 20 mph (32 km/h) on all public roads. This led to the 1907 opening of the Brooklands motor circuit , which inspired

A car considered to be "a sports-car years ahead of its time" is the 1903 Mercedes Simplex 60 hp , described at the time as a fast touring car and designed by Wilhelm Maybach and Paul Daimler . The Mercedes included pioneering features such as

In Italy, a small but wealthy market segment allowed for the manufacture of a limited number of high-performance models directly allied to contemporary Grand Prix machines, such as
3618-627: The thrill of driving, and racing capability. Sports cars originated in Europe in the early 1910s and are currently produced by many manufacturers around the world. Definitions of sports cars often relate to how the car design is optimised for dynamic performance, without any specific minimum requirements; both a Triumph Spitfire and Ferrari 488 Pista can be considered sports cars, despite vastly different levels of performance. Broader definitions of sports cars include cars "in which performance takes precedence over carrying capacity", or that emphasise

The Z-102 had a pressed steel chassis with an alloy body. Everything was produced in-house at Barcelona at Pegaso's own factory, with the exception of coachwork. The Z-102 is powered by a four-cam all-alloy V8 engine featuring dry-sump lubrication. Power went through
3819-478: The war, but a small number of manufacturers returned it to prominence. In 1948, the Porsche 356 was released as the debut model from Porsche. The significance of the Porsche 356 and its successors was described in 1957 as "future historians must see them as among the most important of mid-century production cars". The 1954 Mercedes-Benz 300 SL is another significant car from this era. The 1961 Jaguar E-Type

The Z-102 started life as a pair of prototypes in 1951 with coupe and drophead body styles. Both prototypes had steel bodies which were determined to be too heavy and Pegaso made the decision to switch to alloy bodies to reduce weight. However, the cars were still quite heavy and brutish to drive and racing success

The BMW M3 was released in 1986 and has been produced for every generation since. The 1993-1996 Mercedes-Benz W124 E36 AMG was the mass-produced AMG model. Audi's equivalent division, called "RS", was launched in 1994 with

The term initially described two-seat roadsters (cars without a fixed roof), however, since the 1970s the term has also been used for cars with a fixed roof (which were previously considered grand tourers ). Attributing the definition of 'sports car' to any particular model can be controversial or the subject of debate among enthusiasts. Authors and experts have often contributed their ideas to capture

The Fiat X1/9 (1972-1989) was unusual for its use of a mid-engine design in an affordable roadster model. A late entrant to the affordable roadster market was the 1975 Triumph TR7 , however by the late 1970s the demand for this style of car was in decline, resulting in production ceasing in 1982. The original Lotus Elan (1962-1975) two-seat coupe and roadster models are an early commercial success for
